Abstract:
A detector for determining a position of at least one object, where the detector includes: at least one optical sensor, where the optical sensor has at least one sensor region, where the optical sensor is designed to generate at least one sensor signal in a manner dependent on an illumination of the sensor region by illumination light traveling from the object to the detector; at least one beam-splitting device, where the beam-splitting device is adapted to split the illumination light in at least two separate light beams, where each light beam travels on a light path to the optical sensor; at least one modulation device for modulating the illumination light, where the at least one modulation device is arranged on one of the at least two light paths; and at least one evaluation device, where the evaluation device is designed to generate at least one item of information from the at least one sensor signal.
